alpha taxonomy : the level of taxonomy concerned with the characterisation and naming of species.

beta taxonomy : the level of taxonomy concerned with the arranging of species into a natural system of higher and lower taxa "in beta taxonomy relationships are worked out more carefully on the species level and on that of the higher categories; emphasis is placed on a sound classification"

alpha taxonomy---------------

Naming and describing species

alpha taxonomy begs the fundamental question "what is a species"
Taxonomists distinguish species based on unique morphological or biochemical characters - type specimen, type locality
Names designated based on International Code of Zoological Nomenclature

Beta Taxonomy -- Hierarchy

Individuals

Populations

Species - fundamental unit of classification schemes

Genus

Family

Order

Class

Phylum

Kingdom

Taxonomic names can, and do reflect "natural", i.e. monophyletic groups of organisms; however hierarchical system can be somewhat arbitrary
